    Abstract: Locally backwashing portions of filter media allows a simple and effective design of intake and pretreatment units, as well as their integration. An enclosure is used to limit portions of filter media and backwash them locally by suction, utilizing filtered water from adjacent filter media as the back wash water. Wastewater is produced at small amounts that allows efficient sludge treatment. This design enables water pretreatment at the intake unit, simplifying overall plant design and preventing damage to organisms living outside the intake unit.

    Abstract translation: 过滤介质的局部反冲洗部分可以简单有效地设计进气和预处理单元以及它们的集成。 使用外壳来限制过滤介质的部分并通过抽吸局部反冲洗，利用来自相邻过滤介质的过滤水作为背洗水。 废水产生量少，可以有效地进行污泥处理。 这种设计使得进气单元能够进行预处理，简化了整个设备的设计，并且防止了对进气单元外部生物体的损害。

    Abstract: A water intake and pretreatment system (10) comprising an inlet for delivering water from a natural source to a reservoir (12); said inlet to reservoir having a net screen (16) to prevent entry of organisms above a predetermined size and including a one-way gate (30) to allow organisms to exit the reservoir; said reservoir further comprising a granular filter media for water and algae filtration; and a drainage layer for removal of filtered water from the granular filter media to a drainage outlet. A local backwashing apparatus (40) is included for localized backwashing of the granular filter media.

    Abstract: A local backwashing apparatus 110 for a filtering system comprises an enclosure 119 having an open lower end, positionable above a surface of filter media 92 supported by a drainage layer 96. The enclosure is connected to a mechanical member (300, FIG. 6A) configured to force the enclosure into the filter media and release the force prior to the lower end of the enclosure contacting the drainage layer. The lower end of the enclosure being brought into contact with the drainage layer through a pressure differential between the interior and exterior of the enclosure. A pneumatic system such as an air pump, is in fluid communication with the upper part 127 of the enclosure and is configured to determine an air pressure therein. A pipe system connects the upper part of the enclosure with the pneumatic system and with a discharge structure 132. A control unit is connected to the pneumatic system. Also disclosed is a method of backwashing a filtering system. The backwashing apparatus may be used to pre-treat water.
